しかし、上記従来技術にあっては、図１３に示す様に、屈曲部位における複数のチェーン単位部材間の各屈曲角度が同一でなく、それらの一部が最大屈曲角度Δまで深く屈曲してしまって当該箇所（図１３中、符号Ｄ３と符号Ｄ４の間、符号Ｄ４と符号Ｄ５の間）に一時的に負荷が集中してしまうため、蓄積疲労によるヒンジ部材の切断が発生し易いなど、解決せねばならない課題があった。 However, in the above prior art, as shown in FIG. 13, the bending angles between the plurality of chain unit members at the bending portion are not the same, and some of them are bent deeply to the maximum bending angle Δ. Therefore, the load is temporarily concentrated on the relevant part (between reference signs D3 and D4 and between reference signs D4 and D5 in FIG. 13), so that the hinge member is likely to be cut due to accumulated fatigue. There was a problem that had to be done.

本発明は、上記従来技術に基づく、ヒンジ部材が切断し易い課題に鑑み、中間部位より相反する２方向へ突出する、チェーン単位部材の側板に対し平行な一対の突出部位を有し、一方の突出部位に対し他方の突出部位を、少なくとも一方の突出部位の厚さ分チェーン単位部材の幅方向にずらして配置した主体部材を備え、一方の突出部位に屈曲時当接部位を、他方の突出部位に、隣接するチェーン単位部材間の屈曲角度が最大屈曲角度より小さく設定した角度に達した状態で上記屈曲時当接部位が当接する屈曲時被当接部位を設けた角度規制体を、上記ケーブルチェーンに装着すれば、ケーブルチェーンが最大屈曲状態に至る前に隣接する一方のチェーン単位部材の角度規制体の当接部位が、他方のチェーン単位部材の角度規制体の被当接部位に当接して、ケーブルチェーンの屈曲箇所における隣接するチェーン単位部材間の角度を必要以上に深く屈曲することを防止することによって、ヒンジ部材への負荷集中を抑止する様にして、上記課題を解決する。 The present invention has a pair of projecting portions parallel to the side plate of the chain unit member, which protrude in two directions opposite to the intermediate portion, in view of the problem that the hinge member is easily cut based on the above-described conventional technology. A main member in which the other protruding portion is shifted in the width direction of the chain unit member by at least the thickness of one protruding portion with respect to the protruding portion; An angle restricting body provided with a bent contacted part in which the bending contact part comes into contact with the part in a state where the bending angle between adjacent chain unit members has reached an angle set smaller than the maximum bending angle; If attached to the cable chain, the contact part of the angle restricting body of one adjacent chain unit member is the contacted part of the angle restricting body of the other chain unit member before the cable chain reaches the maximum bending state. The above problem is solved by preventing the load from being concentrated on the hinge member by preventing the angle between the adjacent chain unit members at the bent part of the cable chain from being bent more deeply than necessary. To do.

要するに本発明は、中間部位より相反する２方向へ突出する、チェーン単位部材の側板に対し平行な一対の突出部位を有し、一方の突出部位に対し他方の突出部位を、少なくとも一方の突出部位の厚さ分チェーン単位部材の幅方向にずらして配置した主体部材を備え、一方の突出部位に屈曲時当接部位を、他方の突出部位に、隣接するチェーン単位部材間の屈曲角度が最大屈曲角度より小さく設定した角度に達した状態で上記屈曲時当接部位が当接する屈曲時被当接部位を設けたので、かかる角度規制体を、隣接する一方のチェーン単位部材に装着された角度規制体の内方の突出部位の外側に、他方のチェーン単位部材に装着された角度規制体の外方の突出部位を重ねる様にして装着すれば、屈曲箇所でのケーブルチェーンは、隣接するチェーン単位部材間の屈曲角度が設定角度以上にならないため、ヒンジ部材への負荷集中を抑止することか出来、よってケーブルチェーンの寿命向上を図ることが出来る。
更に、一方の突出部位に伸長時当接部位を、他方の突出部位に、隣接するチェーン単位部材間が伸長状態で上記伸長時当接部位が当接する伸長時被当接部位を設けたので、可動部が水平方向に往復移動自在であっても、伸長箇所でのケーブルチェーンが撓まないため、屈曲開始時に負荷が作用せずスムーズな屈伸を可能にすることが出来る。 In short, the present invention has a pair of projecting portions parallel to the side plate of the chain unit member projecting in two opposite directions from the intermediate portion, and the other projecting portion is at least one projecting portion with respect to one projecting portion. The main body member is arranged so as to be shifted in the width direction of the chain unit member by the thickness of one, and the bending contact portion is bent at one protruding portion, and the bending angle between adjacent chain unit members is the maximum bending at the other protruding portion. Since the bent contact portion is provided so that the bent contact portion comes into contact with the angle set to be smaller than the angle, the angle restricting member is attached to one adjacent chain unit member. If the outer protruding part of the angle restricting body attached to the other chain unit member is overlapped on the outside of the protruding part inside the body, the cable chain at the bent part is connected to the adjacent chain. Since the bending angle between the emission unit member not to exceed a set angle, it can either arresting the load concentration to the hinge member, thus making it possible to life improvement in cable chain.
Furthermore, since the contact part at the time of extension is provided in one projecting part, and the contact part at the time of extension, the contact part at the time of extension is provided in the other projecting part in a stretched state between adjacent chain unit members. Even if the movable part can reciprocate in the horizontal direction, the cable chain at the extended portion does not bend, so that a load does not act at the start of bending and smooth bending and stretching can be achieved.

突出部位を、チェーン単位部材の高さと同等の高さ方向の幅を有する板材としたので、ヒンジ部材が薄く捩れ易いケーブルチェーンであっても、一方の角度規制体における内方板が他方の角度規制体における外方板に当接して捩じれないため、ケーブルチェーンを更にスムーズに屈伸させることが出来る。 Since the protruding portion is a plate material having a width in the height direction equivalent to the height of the chain unit member, even if the hinge member is a thin and easily twisted cable chain, the inner plate in one angle regulating body is the other angle The cable chain can be bent and stretched more smoothly because it does not twist against the outer plate of the regulating body.

内方の板材の外面又は外方の板材の内面にストッパーを設け、外方の板材又は内方の板材に、外方の板材の内面又は内方の板材の外面で開口する、上記ストッパーの収容部を形成し、上記ストッパーを屈曲時当接部位とし、上記収容部の周壁部における、設定角度屈曲時にのみ当接する部位を屈曲時被当接部位としたり、内方の板材の外面又は外方の板材の内面にストッパーを設け、外方の板材又は内方の板材に、外方の板材の内面又は内方の板材の外面で開口する、上記ストッパーの収容部を形成し、上記ストッパーを伸長時当接部位とし、上記収容部の周壁部における、伸長時にのみ当接する部位を伸長時被当接部位としたり、或いは内方の板材の外面又は外方の板材の内面にストッパーを設け、外方の板材又は内方の板材に、外方の板材の内面又は内方の板材の外面で開口する、上記ストッパーの収容部を形成し、上記ストッパーを屈曲時当接部位及び伸長時当接部位とし、上記収容部の周壁部における、設定角度屈曲時にのみ当接する部位を屈曲時被当接部位と、伸長時にのみ当接する部位を伸長時被当接部位としたので、内外方の板材間を接触させるか、或いは極微小な隙間を形成させるだけで対応可能なため、装着状態でのコンパクト化を図ることが出来る。
而も、収容部を、チェーン単位部材間の屈曲中心を中心とした円弧状に形成したり、Ｖ字切欠としたので、簡単な構成でケーブルチェーンの過度の屈曲を防止出来る。 A stopper is provided on the outer surface of the inner plate member or on the inner surface of the outer plate member, and the stopper is accommodated in the outer plate member or the inner plate member, which opens at the inner surface of the outer plate member or the outer surface of the inner plate member. And the stopper is used as a contact part when bent, and a part of the peripheral wall part of the housing part that contacts only when bent at a set angle is used as a contact part when bent, or an outer surface or an outer side of an inner plate member. A stopper is provided on the inner surface of the plate material, and the stopper plate is formed in the outer plate material or the inner plate material so as to open at the inner surface of the outer plate material or the outer surface of the inner plate material, and the stopper is extended.

The outer plate on the inner plate or the inner plate Forming the stopper accommodating portion that opens at the inner surface of the inner plate or the outer surface of the inner plate member, and using the stopper as a contact portion at the time of bending and a contact portion at the time of extension. The part that only contacts is the contacted part when bent and the part that contacts only when extended is the contacted part when extended, so it is only necessary to contact the inner and outer plates or to form a very small gap Because it is compatible, it can be made compact in the mounted state.
In addition, since the accommodating portion is formed in an arc shape centering on the bending center between the chain unit members or is formed in a V shape, excessive bending of the cable chain can be prevented with a simple configuration.

屈曲時当接部位を、一方の板材の先端部の下方部位に形成した傾斜辺部とし、屈曲時被当接部位を、他方の板材に設けたストッパーとしたので、簡単な構成でケーブルチェーンの過度の屈曲を防止することが出来る。 Since the bent contact portion is an inclined side formed in the lower part of the tip of one plate material and the bent contact portion is a stopper provided on the other plate member, the cable chain can be constructed with a simple configuration. Excessive bending can be prevented.

伸長時当接部位を、一対の板材の少なくともどちらか一方の先端面とし、伸長時被当接部位を、中間部位における上記先端面と対向する側面とし、前記先端面及び側面の一方又は両方を、屈曲過程において両者が当接しない様に形成したので、簡単な構成でケーブルチェーンの伸長姿勢を維持することが出来る。 The abutting part at the time of extension is at least one of the tip surfaces of the pair of plate members, the abutted part at the time of extension is a side surface facing the tip surface at the intermediate part, and one or both of the tip surface and the side surface are The cable chain is formed so as not to come into contact with each other in the bending process, so that the extended posture of the cable chain can be maintained with a simple configuration.

内方の板材の外側面と外方の板材の内側面との間に隙間を形成したので、隣接する一方の角度規制体の内方の板材と、他方の角度規制体の外方の板材とが当たらないため、摺接による粉塵が発生せず、クリーンルームで使用可能にすることか出来る。 Since a gap is formed between the outer side surface of the inner plate member and the inner side surface of the outer plate member, the inner plate member of one adjacent angle restricting body and the outer plate member of the other angle restricting member Can be used in a clean room without dust generated by sliding contact.

In the process, the angle restricting bodies 1a, 1b to be attached to the inner plate members 14 of the angle restricting bodies 1, 1a ... already attached to the adjacent one of the chain unit members D1, D2,. The outer plate material 15 is overlapped, and the stopper 16 is accommodated in the accommodating portion 17 (the window portion 18 or the V-shaped notch 19), and finally the upper portion in the engaging recess G of the chain unit members D2, D3. The engagement portions 13 are repeatedly fitted, and the angle restrictors 1 ′, 1a ′,... Are attached to the other side of the cable chain W in the same manner.

そして、隣接するチェーン単位部材Ｄ１、Ｄ２…間が伸長状態より屈曲し始めると、接触状態の伸長時当接部位８（ストッパー16、中間部位２の側面2a、2b）と伸長時被当接部位９（窓部18の一端縁部18a 、Ｖ字状切欠19の一辺部19a 、内外方の板材14、15の先端面14a 、15a ）が離間して、最終的に屈曲時当接部位６（ストッパー16、22）が屈曲時被当接部位７（窓部18の一端縁部18a 、Ｖ字状切欠19の一辺部19a 、内方の板材14に形成した傾斜辺部20）に当接するまで隣接するチェーン単位部材Ｄ１、Ｄ２…間が屈曲するため、隣接するチェーン単位部材Ｄ１、Ｄ２…間が最大屈曲角度Δまで屈曲する前に、屈曲時当接部位６が屈曲時被当接部位７に当接する様にすれば、隣接するチェーン単位部材Ｄ１、Ｄ２…間が最大屈曲角度Δまで屈曲せず、而も屈曲時の負荷は角度規制体１、1a…、1'、1a' …側に作用することになる。 When the adjacent chain unit members D1, D2,... Begin to bend from the extended state, the contact part 8 when extended (the stopper 16, the side surfaces 2a and 2b of the intermediate part 2) and the contacted part when extended. 9 (one end edge portion 18a of the window portion 18, one side portion 19a of the V-shaped cutout 19, and the front end surfaces 14a and 15a of the inner and outer plate members 14 and 15) are separated from each other, and finally the bent contact portion 6 ( The stoppers 16 and 22) are in contact with the contacted portion 7 when bent (one end edge portion 18a of the window portion 18, one side portion 19a of the V-shaped cutout 19, and the inclined side portion 20 formed on the inner plate member 14). Since the adjacent chain unit members D1, D2... Are bent, the bent contact portion 6 is bent before the bent chain member D1, D2. , The adjacent chain unit members D1, D2... Do not bend up to the maximum bending angle Δ and are bent. Load angle regulating member 1,1a ..., 1 ', 1a' acts on ... side.

更に、使用状態のケーブルチェーンＷにおける伸長部位は伸長時当接部位８と伸長時被当接部位９が当接状態であることから伸長状態を維持して下方に撓まず、ケーブルチェーンＷが捻じれ易くても、隣接する一方の角度規制体１、1a…、1'、1a' …の内方の板材14の外側に、他方の角度規制体1a、1b…、1a' 、1b' …の外方の板材15があるため、角度規制体１、1a…、1'、1a' …を装着したケーブルチェーンＷは捻じれず、更に隣接する一方の角度規制体１、1a…、1'、1a' …における内方の板材14と、他方の角度規制体1a、1b…、1a' 、1b' …における外方の板材15との間に隙間ｈがあれば、両者の摺接による粉塵が発生しない。 Further, since the extended portion of the cable chain W in use is in the contact state between the contact portion 8 when extended and the contacted portion 9 when extended, the cable chain W is twisted without maintaining the extended state and being bent downward. Even if it is easy to be done, the other angle restricting bodies 1a, 1b ..., 1a ', 1b' ... of the other angle restricting bodies 1, 1a ..., 1 ', 1a' ... Since there is an outer plate 15, the cable chain W to which the angle restrictors 1, 1a, 1 ', 1a' ... are not twisted, and one of the adjacent angle restrictors 1, 1a, 1 ', 1a is not twisted. If there is a gap h between the inner plate 14 at ... and the outer plate 15 at the other angle restrictors 1a, 1b, 1a ', 1b' ..., dust will be generated due to sliding contact between them. do not do.
